MoIs'rENEn FOR EivvELors, POSTAGE-STAMPS, &c.

To all whom it may concern:

Be it known that I, MARY F. BIsHor, a citizen of the United, States andresiding at the city of Philadelphia, county, of Philadelphia, and Stateof Pennsylvania, have invented certain new and useful Improvements inMoistener for Envelops, Postage Stamps, &c.; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to certain new and useful improvements in amoistener for envelops, and it consists in a rotary holder for a brushor spongue that'is adjustably mounted on a flexibledrive shaft, forbeing immersed in a liquid bath and subsequently secured above thelatter whereby an envelop, or other article, may be moved under thebrush and in contact therewith to be moistened thereby.

The primary object of this'invention resides in an improved moistener orapplicator which is mounted for movement into and from a liquidcontainer and rotated or set in motion while an envelop or the like ismoved across and in contact therewith.

The invention further resides in the featur'es of construction and thearrangements and combinations of parts hereinafter described, claimedand illustrated in the accompanying drawing wherein Figure 1 is avertical section through the preferred embodiment of the invention,portions being left in elevation; and

Fig. 2 is a similar viewillustrating the modificaton of the invention,the well being 7 adjustable vertically on its support.

At a suitable distance from the well opening 3, the upper face of thebase is formed with a second opening in which is disposed a case 6 thatreceives support on the bottom of the base chamber and houses a motor,either of the mechanical type, as a' spring motor, or of the electricaltype, in whlch Application filed.

Specification of Letters Patent. 7 Patented Aug. '7, 1917 latterinstanc'e' suitable current wires (not shown) are provided. Fixed on thecase 6 is agooseneck tubular-housing 7 that has its shorter arm 8terminating directly over the well 5, and through this housing is passedthe flexible shaft 9 Whichhas connection with the motor at one end andhas its oppositeendextended beyond the housing or tubular" support forconnection with a sponge or brush.

The numeral 10' indicates a sleeve that is vertically adjustable on theprojecting apply an adhesive to a surface. The screw 11 is loosened andthe sleeve dropped to im: merse the sponge in the bath contained in thewell, after which the sleeve is elevated to the desired height and fixedin said ad-' justment by tightening the set screw. The motor is nowstarted to rotate the sponge as an envelop is shifted therebeneath overthe broad flat surface afforded by the table 2.

The modified form of the invention comprises a motor case 14 whichconstitutes the supporting base and from which rises the goose-necktubular support 15 for housing the flexible motor shaft 16, th latterhaving the sleeve 10'adjustably secured thereon by screw 11. The well17, in this instance,

- is cup-shaped and has a flat top 18 constituting a broadsupportingtable for the envelop, said top having a central opening 19through which the sponge 13 is lowered for immersion in the bath. Thewell is adjustable up and down the longer arm of the tubular support bymeans of the ring clamp 20, carrying the well, and set screw 21.

In either form, the envelop is aflorded a broad support over which it isshifted under .therotating sponge, the latter, through its rotaryrubbing action, thoroughly moisten ing the dried mucilaginous film toefl'ect perfect adhesion. 7

The terms envelop and ,moistener have been used herein in their broaderopen wellczsuppo'rted'within saidtable and below the plane thereof,a-motor ithin said base, a tubular goose-neck support rislng from a themotor and terminating directly oyer the well, a flex ible motor. shafthoused byith e tubularsupport and extending beyondthe free end of thelatter, a sleeve adjustable .on the projectingend of the shaft,
